• Primary Route: I-5 North → OR-58 East → US-97 North → I-84 East
  1. I-5 N (Eugene → Salem, 65 mi)
  2. OR-58 E (Willamette Pass, 100 mi) – scenic, winter chains often required

Key Considerations

• Willamette Pass (OR-58, 5,128 ft): Snow/ice Nov–Apr. Check TripCheck. Carry chains.
• Fuel: Fill in Eugene or Bend; long stretches without services.
• Time zones: Oregon (PT) → Idaho (MT) at Oregon/Idaho border (gain 1 hour).
• Scenic stops: Salt Creek Falls, Newberry Volcanic Monument, Snake River Canyon.

Allow 9–10 hours for a relaxed trip with breaks. Winter: add 2+ hours or delay.
